Patrick M Kleeman
Patrick Kleeman is a Supervisory Ecologist at the Western Ecological Research Center.
Patrick Kleeman's research focuses on the ecology and conservation biology of amphibians. Topics of study within these categories include population demography through capture-mark-recapture methods, habitat use by using radiotelemetry, and phenology of breeding as evidenced by vocalizations. His research also examines what role stressors such as environmental contaminants, disease, and climate may have on amphibian populations. In addition to amphibians, he also works with island night lizards (Xantusia riversiana) on San Nicolas Island and Townsend's big-eared bats (Corynorhinus townsendii) at Point Reyes National Seashore.

Time to detection data for Point Reyes pond-breeding amphibians, 2017 Time to detection data for Point Reyes pond-breeding amphibians, 2017
Occupancy models provide a reliable method of estimating species distributions while accounting for imperfect detectability. The cost of accounting for false absences is that detection and nondetection surveys typically require repeated visits to a site or multiple-observer techniques. More efficient methods of collecting data to estimate detection probabilities would allow additional...
Occurrence of Amphibians in Northern California Coastal Dune Drainages Occurrence of Amphibians in Northern California Coastal Dune Drainages
Many coastal dune ecosystems have been degraded by non-native dune vegetation, but these systems might still provide valuable habitat for some taxa, including amphibians. Because restoration of degraded dune systems is occurring and likely to continue, we examined the occurrence of amphibians in drainages associated with a coastal dune ecosystem degraded by invasive plants (European...
California Red-Legged Frogs in Point Reyes Coastal Dune Drainages (2015) California Red-Legged Frogs in Point Reyes Coastal Dune Drainages (2015)
California Red-legged Frogs (Rana draytonii) are typically regarded as inhabitants of permanent ponds, marshes, and slow-moving streams, but their ecology in other habitats, including coastal dunes, remains obscure. To avoid and minimize potential negative effects of dune restoration activities, we studied the spatial ecology, habitat selection, and survival of California Red-legged...

Effect of amphibian chytrid fungus (Batrachochytrium dendrobatidis) on apparent survival of frogs and toads in the western USA Effect of amphibian chytrid fungus (Batrachochytrium dendrobatidis) on apparent survival of frogs and toads in the western USA
Despite increasing interest in determining the population-level effects of emerging infectious diseases on wildlife, estimating effects of disease on survival rates remains difficult. Even for a well-studied disease such as amphibian chytridiomycosis (caused by the fungus Batrachochytrium dendrobatidis [Bd]), there are few estimates of how survival of wild hosts is affected. We applied...

Linking variability in climate to wetland habitat suitability: Is it possible to forecast regional responses from simple climate measures? Linking variability in climate to wetland habitat suitability: Is it possible to forecast regional responses from simple climate measures?
Temporary wetlands have value to both ecological and social systems. Interactions between local climate and the surrounding landscape result in patterns of hydrology that are unique to temporary wetlands. These seasonal and annual fluctuations in wetland inundation contribute to community composition and richness. Thus, predicting wetland community responses to environmental change is...

Distribution, habitat, and population size of Island Night Lizards on San Nicolas Island, California Distribution, habitat, and population size of Island Night Lizards on San Nicolas Island, California
The Island Night Lizard (Xantusia riversiana) was removed from the federal list of threatened species in May 2014. This strongly differentiated species is endemic to 3 of the southern California Channel Islands—San Clemente, San Nicolas, and Santa Barbara. Suitable habitat for Island Night Lizards is extensive on San Clemente Island, and the species is abundant there. Habitat is limited...

Quantifying climate sensitivity and climate-driven change in North American amphibian communities Quantifying climate sensitivity and climate-driven change in North American amphibian communities
Changing climate will impact species’ ranges only when environmental variability directly impacts the demography of local populations. However, measurement of demographic responses to climate change has largely been limited to single species and locations. Here we show that amphibian communities are responsive to climatic variability, using >500,000 time-series observations for 81...

Population trends, survival, and sampling methodologies for a population of Rana draytonii Population trends, survival, and sampling methodologies for a population of Rana draytonii
Estimating population trends provides valuable information for resource managers, but monitoring programs face trade-offs between the quality and quantity of information gained and the number of sites surveyed. We compared the effectiveness of monitoring techniques for estimating population trends of Rana draytonii (California Red-legged Frog) at Point Reyes National Seashore, California...

California Red-legged Frogs (Rana draytonii) are typically regarded as inhabitants of permanent ponds, marshes, and slow-moving streams, but their ecology in other habitats, such as drainages among coastal dunes, remains obscure. Because coastal dune ecosystems have been degraded by development, off-highway vehicle use, stabilization, and invasive species, these unique ecosystems are the...

Large-scale recovery of an endangered amphibian despite ongoing exposure to multiple stressors Large-scale recovery of an endangered amphibian despite ongoing exposure to multiple stressors
Amphibians are one of the most threatened animal groups, with 32% of species at risk for extinction. Given this imperiled status, is the disappearance of a large fraction of the Earth’s amphibians inevitable, or are some declining species more resilient than is generally assumed? We address this question in a species that is emblematic of many declining amphibians, the endangered Sierra...

Wetland occupancy of pond-breeding amphibians in Yosemite National Park, USA Wetland occupancy of pond-breeding amphibians in Yosemite National Park, USA
We estimated wetland occupancy and population trends for three species of pond-breeding anurans in Yosemite National Park from 2007-2011. We used a double survey technique in which two observers independently surveyed each site on the same day. Double surveys allowed us to calculate detectability for the three most common anurans within the park: Rana sierrae, Anaxyrus canorus, and...

Pesticides in amphibian habitats of Central and Northern California, USA Pesticides in amphibian habitats of Central and Northern California, USA
Previous studies have indicated that toxicity from pesticide exposure may be contributing to amphibian declines in California and that atmospheric deposition could be a primary pathway for pesticides to enter amphibian habitats. We report on a survey of California wetlands sampled along transects associated with Lassen Volcanic National Park, Lake Tahoe, Yosemite National Park, and...
